Thanks for the help coming in on the gearing still not really sure on which way to go for starting point. And would the 5" pulley on motor and gear box be to much for it being 1:1 to the gearbox as far as gearbox rpm.And as far as the rear sprockets if it makes it easier or any difference I can get diff rear sprockets those are just some I have. Thanks!!

Is it required to replace the flywheel on a vanguard 16hp twin to remove the governor? I'm not going to be revving it massively high it's just to put a different carb on it. If so what would the effects be on keeping it stock? Thanks

Hi allBeen into doing mowers up for some time now as I'm 16 and have been working on weekends for some years. I've managed to scrape around and getting my first mower this weekend - a countax k14T. As for intelligence Irent my own workshop where I repair and restore small engines and machinery so will be more than happy to help with eny issues.I haven't really seen mower racing in the UK as much but plenty of tracks around the place for trials.Hope to talk to you soon!
